WebFeb 23, 2024 · In C4 plants, photosynthetic tissues differ structurally and functionally from those in C3 plants. For example, bundle sheath cells in C4 plants are effectively shielded from the atmosphere by a ring of mesophyll cells (Fig. 5.20). This arrangement allows the mesophyll cells to regulate. Figure 5.20 Leaf anatomy in a C4 plant.

WebThe Calvin cycle (synthesis) uses energy from the light reactions to incorporate CO2 from the atmosphere into sugar. In the light reactions, light energy absorbed by chlorophyll in the thylakoids drives the transfer of electrons and hydrogen from water to NADP+ (nicotinamide adenine dinucleotide phosphate), forming NADPH.
